Title: Colour television receiver
IPC: H04N11/16
Filed: 1972-06-20
Abstract: 1400169 Colour television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 June 1972 [25 June 1971 16 July 1971] 28891/72 Heading H4F The output of an (R-Y) reference oscillator 18 in a PAL colour television receiver is inverted during alternate line periods, to ensure correct operation of the (R-Y) demodulator, using a transformer 26 whose primary is connected between the oscillator output and earth and whose secondary has its centre point earthed so as to provide anti-phase signals at its ends. These anti-phase signals are passed to the R-Y demodulator 7 alternately by using two series connected diodes 24, 25 across the transformer secondary, the diodes being gated on alternately by two anti-phase half-line frequency square waves supplied to the ends of the transformer secondary, the signal to the R-Y demodulator being taken from the connection 29 between the diodes. In one embodiment (Fig. 4, not shown] the R-Y oscillator is caused to operate at Œ(B-Y) phase by means of an automatic frequency control circuit. In an alternative embodiment, Fig. 1, a second transformer 13 and pair of diodes 14, 15, gated by the squarewave outputs of flip-flop 21 are provided to invert alternate bursts fed via burst gate 16 to R-Y oscillator 18 which operates at + (R-Y) or - (R-Y) phase in dependence on the phase of the outputs of flip-flop 21 relative to the received bursts. The operation of the transformers 13, 26 and diodes 14, 15, 24, 25 causes the signal fed to demodulator 7 always to be in phase with the received R-Y modulation axis, which ever phase the outputs of flip-flop 21 are in relative to the received signal. The B-Y oscillator 19 receives anti-phase bursts from transformer 13 and operates at + (B-Y) phase.

Abstract: 147,393. Laurency, G. C., and Vigier, M. Nov. 24, 1919. Carding-engines; combing-machines. - Fibres are removed in tufts from the carding-engine cylinder A, Fig. 1, by a cylinder B provided with sections 1 of card wire, alternating with raised smooth sections 2. The wire in the card wire sections is arranged in progressively closer formation in the direction of rotation. The surface of the smooth sections is in the same circle at the points of the wires. The cylinder is heated bv a steam coil 3. As the tufts are detached from the cylinder A thev are supported by the succeeding smooth section and the rear ends combed. They are then ironed and smoothed between the heated sections 2 and a belt C moving more slowly than the cylinder B. The forward ends of the tufts are also, by the action of the belt, detached from the card wire sections 1 and combed by them. A belt D moving in the opposite direction to the belt C detaches the tufts from the cylinder B and passes them forward in co-operation with the belt C. Succeeding tufts are also pieced together at this point. On leaving the bands C, D, the pieced sliver is deposited on a narrow endless band E moving over cylinders 10, 11 and advancing gradually across the cylinder. The sliver is detached by a metallic piece 20, Fig. 3, and is passed through rubbing- aprons 16, 17 to bobbins 18 or a can 19. Dirt and short fibres are removed from the cylinder B by a brush 4<1>, the dirt being thrown on to an apron 5 and the fibres being removed by a wire stripping-brush 6 and comb 7 and thrown on to an apron 8. A brush 4 rotating more slowly than the band C straightens the fibres before they pass between the band and the cylinder B.

Title: Drill stem testing device
IPC: E21B49/08
Filed: 1948-11-11
Abstract: 654,862. Well-boring apparatus. STANDARD OIL DEVELOPMENT CO. Nov. 11, 1948, No. 29376. Convention date, Dec. 30, 1947. [Class 85] An assembly, which permits the sealing off of the lower portion of a borehole and the obtaining of a sample of fluid without the removal of the drill stem and cutter head, comprises a packer unit disposed between said stem and head and a sample bottle unit. The packer 12 is expanded when drill mud under pressure passes from within the tubular body 1 of the packer unit through one or more ports 4 when the spring-biased valves 6 are withdrawn off the seats 5. The sample bottle unit comprises. a bottle 15 which is connected to a piston guide body 20 by a body 16, and on said body slides a piston 22 carrying spring hook fingers. A piston 22 fits the bore of the drill stem so that the sample bottle unit is forced by the drill mud down the interior of the drill stem until the body 21 strikes the bottom of the bore when the piston 22 then continues to move downwards against the action of the spring 25 to cause the fingers to be forced outwards as they pass over the body 16 so that they engage and force downwardly the heads 11 of the valves 6, so permitting expansion of the packer. Further downward movement of the piston causes it to engage and force down rods 27 that are connected to a valve 33 so that this valve opens to permit a sample of fluid to pass upwards through the passage 40 and by the non-return valve 42 into the bottle. On decreasing the fluid pressure in the drill stem, the plunger is moved upwards by the spring 28, the valve 33 closes and the spring fingers contract so freeing the valves of the ports 4.

Abstract: 776,370. Ultrasonic inspection devices. INSTITUT DE RECHERCHES DE LA SIDERURGIE. Oct. 15, 1954 [Oct. 28, 1953], No. 29725/54. Class 118 (2). [Also in Groups XXXIX and XL (b)] In ultrasonic examination of metals in which a trace appears on a cathode-ray oscillograph photo-cells associated with the screen operate means to produce a record of defects in the specimen. General arrangement (Fig. 1).-Pulses are produced and received by a piezo-electric transducer 9 which is traversed along the specimen in a number of parallel lines. The output of the detector is amplified, but instead of being applied to the Y plates, the X plates being provided with a linear sweep voltage, is applied to the grid of the cathode-ray tube 4 so as to make the trace visible only when the reflected pulse is received. Adjacent the screen of the cathode-ray tube is a row 5 of photo-electric cells (to be described). Thus the cell which is energized represents the depth of the defect. Each cell is associated with one of a number of styli 7 arranged transversely to a recording strip 8 synchronized with the transducer movement which thus make marks such as 14, 15 or 16 which represent by their position along the strip the position of the flaw along the specimen and by their position in a direction transverse to the strip travel the depth of the flaw. The pulse which marks the strip may also, or alternatively, be used to operate a warning loudspeaker. Transducer (Fig. 3).-A piezo-electric quartz transducer 9 is secured to rod 34 rigid with a stationary spindle 35. The quartz is contained in a liquid-filled chamber sealed by side-plates 36. A rubber case 37 held between side-plates 36 and further plates 38 closes the edge of the chamber and is such as to be flattened by the weight of the assembly so as to provide a good contact with the substance under test. Spindle 35 is supported in a yoke on rollers 39 and may be lifted by handles 40 (Fig. 1). The photo-cell assembly consists of a number of photo-cells 5 mounted on a curved block of transparent plastic material which fits the screen of the cathode-ray tube.
